Disassembly And Assembly Of Subassemblies: Differential: Disassembly

CAUTION: Use protective plates in the vise to prevent damage to the differential.

NOTE: Prior to disassembly, measure the backlash of the side gear and pinion gear. Check for damaged or worn gears and a cracked or damaged gear case. If not as specified, replace the differential assembly.

1. Use Dial Indicator/Magnetic Base to measure the backlash of the side gears and pinions. If backlash is not within specification, replace the differential as an assembly.
   1. Install the LH and RH halfshafts.
   2. Support the halfshafts on V-blocks.
   3. Measure the backlash of the side gears and pinions.
